Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal. Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.

Characterizing patents as “a lottery ticket to a lawsuit” and noting the company’s surprise at how little interest the big car companies have shown thus far in electric car technology, Musk explained,

We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform. Technology leadership is not defined by patents, which history has repeatedly shown to be small protection indeed against a determined competitor, but rather by the ability of a company to attract and motivate the world’s most talented engineers. We believe that applying the open source philosophy to our patents will strengthen rather than diminish Tesla’s position in this regard.

Tesla’s patents, like all patents, exist to protect inventions which are useful (have utility), novel (don’t already exist), and non-obvious (meaning that a person with ordinary skill in the field of the invention would not reasonably be expected to assemble or anticipate the invention). Patents come in three flavors:

Utility patents, which protect the function of a process, machine, or manufacture. These have a lifetime of 20 years from the filing date before the patent expires.

Design patents, which protect the form or ornamental design of a product. These have a lifetime of 14 years from the issue date before the patent expires.

Provisional patents, which are not actually patents — they’re just placeholder applications for utility patents, letting other people know to back off. These can be held for one year from the filing the date before the utility patent application must be filed.

One of Tesla’s patents.

Although you wouldn’t know it from the media coverage, the information contained within the patents is a far cry from source code (or a recipe book, or blueprints). Because patents are publicly published upon issuance, extraneous details are rarely included where they do not directly relate to the unique features of the invention. Additionally, patent filings are intentionally written very broadly so as to provide the patent holder with as much legal protection for their design as possible. Without CAD files, schematics, a bill of materials, and other crucial engineering documents, patents are not enough to implement designs.

So while Tesla may no longer be filing aggressive lawsuits for patent infringement, “open source” isn’t the greatest analogy because a) the inventions were already public, and b) the write-ups do not contain the necessary information to replicate the design. This doesn’t mean that Tesla is a bad company; more likely, it just means that Musk has a good understanding of whatwillgeneratebuzz in the media. “Copyleft,” a more accurate term, just doesn’t have the same ring.

While many are calling Musk’s move unprecedented, the auto industry does in fact have fairly recent experience with patents being opened up for industry-wide use. In the 1960s, Volvo shared the patent for the three-point safety belt, a move which is estimated to have saved over a million lives since then. And in the 1970s, General Motors shared its invention of the catalytic convertor, which scrubs smog-forming pollutants out of exhaust. Auto companies also work cooperatively all the time, making business deals to license patents and work on individual shared projects together. But rarely (never?) do companies issue the wide open invitations of the sort that Tesla just did. I’m rarely (never?) interested in cars, but Tesla’s announcement just made the field a lot more interesting. So that’s something.

Notes From A Queer Engineer is a recurring column with an expected periodicity of one month. The subject matter may not be explicitly queer, but the industrial engineer writing it sure is. This is a peek at the notes she’s been doodling in the margins.

Laura Mandanas is a Filipina American living in Brooklyn. By day, she works as an industrial engineer. By night, she is beautiful and terrible as the morn, treacherous as the seas, stronger than the foundations of the Earth. All shall love her and despair.
